Thanks

Hey, I have a question that hopefully someone can answer for me. The other day I was listening to music on my computer, not too loud, and all of a sudden when it was switching to the next track, my sub made a "pop" and started to make this high pitch squealing. I turned it off, unplugged everything from it, except the power, and turned it back on. And it is still making that noise. Is it the Amp that is messed up? Or what do you guys think is the problem? Thanks for the help.
